| 摘 要： | 本文通过对相山火山盆地基底震旦系浅变质岩、盖层火山岩稀土元素分布特征的研究,探讨相山火山岩的物质来源及岩石成因,认为相山火山岩主要是上部地壳重熔的产物,其岩石成因应属于重熔型花岗岩的范畴。

| Abstract: | Based on the study on REE distribution characteristics of Sinian low-grade metamorphic rocks of the basement and cover volcanics,the author makes a discussion on the material source and the gene-sis of Xiangshan volcanics,and suggests that Xiangshan volcanics came mostly from the remelting of the upper crust,and the genesis should be attributed to the category of remelted granites. |
